Question

Edgar is trying out for a junior bowling league. He bowled some extra games Friday and Saturday to practice. On Friday, he paid $7 to rent a pair of shoes and x dollars an hour to bowl. He went to a different bowling alley on Saturday, where he paid $5 to rent shoes and y dollars an hour to bowl. Edgar bowled 2 hours on Friday and 3 hours on Saturday.
Pick all the expressions that represent how much Edgar spent bowling last Friday and Saturday.

Answer 1

Let's break down the costs for both days.

On Friday:

- Shoe rental: $7
- Bowling cost per hour: x dollars
- Hours bowled: 2

Total cost for Friday: $7 (shoe rental) + 2 * x (cost of bowling for two hours) = $7 + 2x.

On Saturday:

- Shoe rental: $5
- Bowling cost per hour: y dollars
- Hours bowled: 3

Total cost for Saturday: $5 (shoe rental) + 3 * y (cost of bowling for three hours) = $5 + 3y.

To represent the total amount spent on both days, you'd add the cost for Friday and Saturday together:

Total cost for Friday and Saturday: ($7 + 2x) + ($5 + 3y).

Simplifying that, we get the total cost:

Total cost = $7 + $5 + 2x + 3y.

Combine the constants:

Total cost = $12 + 2x + 3y.

Now, any expression that is equivalent to $12 + 2x + 3y would represent how much Edgar spent bowling last Friday and Saturday.
